KA-Band Solid State Local Oscillator for AN/SPN-42 Application.

A Ka-band local oscillator was developed that provides 16 milliwatts of CW RF power using a solid state Gunn source. The source operates at 33140MHZ plus or minus 0.5MHZ, and will be used in the AN/SPN-42 Carrier Landing System. The local oscillator has been tested over the ambient temperature range -40C to +71C. Over this temperature range it showed a power stability of plus or minus 0.15db, and a frequency stability of plus or minus 900KHZ. It is recommended that the local oscillator be incorporated into an AN/SPN-42 system and evaluated under actual operating conditions. (Author)
